AMSAT Submits Letter of Intent for NASA SLS CubeSat Opportunity on Artemis III, IV, and V

On May 31, 2026, AMSAT submitted a Letter of Intent (LOI) to NASA Marshall Space Flight Center in response to a Sources Sought Notice for CubeSat secondary payload opportunities aboard the Space Launch System (SLS) on the Artemis III, IV, and V missions.

The LOI expresses strong interest in developing and flying an AMSAT-designed CubeSat payload on one or more of these missions. It highlights the strategic alignment between the opportunity and AMSAT’s ongoing GOLF (Greater Orbit, Larger Footprint) program, which is building the technologies and operational experience needed for amateur radio satellites in progressively higher orbits—from LEO through MEO to HEO.

A high-Earth deployment would provide an outstanding environment to qualify key GOLF technologies—particularly radiation-tolerant electronics, advanced Software-Defined Radio (SDR) transponders, three-axis attitude determination and control, and deployable/steerable solar arrays—in the demanding thermal, radiation, and trajectory conditions beyond low Earth orbit. Such a mission would significantly expand amateur radio’s “larger footprint,” deliver critical flight heritage, and create clear synergies with NASA’s exploration, technology demonstration, and public engagement goals.

The LOI emphasizes AMSAT’s long heritage of successful CubeSat missions (including the Fox series flown via NASA CSLI/ELaNa) and its robust portfolio of educational and university partnership programs. These include the CubeSat Simulator Program used worldwide in schools and universities, collaborations such as the radiation experiment from Vanderbilt University and imaging payloads from Virginia Tech on Fox satellites, broader STEM outreach through live satellite contacts and telemetry projects, and active mentorship of student teams and early-career professionals.

AMSAT is prepared to deliver a flight-ready CubeSat payload, leveraging its proven engineering pipeline, dedicated volunteer technical team, and sustainable funding model of membership support, targeted donations, and grants. AMSAT proposes a 6U-class spacecraft (<14 kg) featuring deployable solar arrays and an AMSAT-developed amateur radio communications system supporting VHF uplink/UHF downlink plus 5 GHz uplink and 10 GHz downlink. A precursor 3U technology demonstrator, GOLF-TEE, is under construction with completion targeted by the end of the year; if selected, AMSAT would pivot development toward the 6U configuration in collaboration with partners. Ground operations would leverage the global amateur radio community for telemetry reception via AMSAT’s analysis tools, supported by dedicated AMSAT command stations.

The organization is genuinely excited about the prospect of contributing an AMSAT-developed CubeSat to the Artemis program—advancing amateur radio’s historic role in space exploration, qualifying technologies for future HEO and lunar missions, and inspiring students and the global public through meaningful educational partnerships.

OscarWatch Tracker: A New Satellite Tracking Program from MM9SQL

A new multi-platform desktop satellite tracking application for amateur radio operators, OscarWatch Tracker, has been released and is under active development. Developed by Peter Goodhall, MM9SQL, and hosted on GitHub, OscarWatch provides an integrated environment for tracking AMSAT and other amateur satellites, predicting passes, managing Doppler-corrected frequencies, and optionally automating rotator and radio control—all from a single map-centered interface.

Key Features

OscarWatch is tailored for VHF/UHF satellite operators working FM cubesats (e.g., SO-50, ISS), linear transponders (e.g., RS-44, FO-29), and similar modes. It assumes familiarity with basic concepts like azimuth, elevation, and Doppler but automates the calculations and hardware interactions to let operators focus on making contacts.

  • Visual Tracking: World map with satellite subpoint, ground track, and footprint overlays (with optional motion arrows and greyline terminator). Includes a polar sky plot relative to your QTH. Support for time scrubbing to preview passes without affecting live hardware. Optional DX station grid marker with live Az/El from the remote location.
  • Pass Predictions: List of upcoming passes with TCA (time of closest approach/max elevation), filters for minimum elevation and duration. Features include a pass planner with multi-station profiles and .ics calendar export, plus a mutual pass finder for two-station coordination.
  • Frequency Management: Built-in transponder database with live Doppler-corrected uplink/downlink frequencies. Supports RX offsets (separate for Voice/CW on linear modes), CTCSS tones, and easy toggling between modes. Includes a transponder database editor for custom additions and updates from the published JSON source.
  • Hardware Integration: Optional serial CAT control for supported radios (including Icom IC-910/9100/9700/705, Yaesu FT-847/817/818/991 series, Kenwood TS-2000 beta) with Doppler tracking, satellite/split modes, and CTCSS handling. Dual-radio support for full-duplex setups. Rotator control for Yaesu GS-232 and EasyComm-compatible controllers (including SPID), with manual park and smart azimuth options for 450° rotators.
  • Additional Tools: Voice announcements for satellite rising, automatic pass WAV recording, Cloudlog integration for frequency logging, and live telemetry (Az/El, range, altitude).

OscarWatch does not decode telemetry or serve as primary logging software; it complements existing tools as a pass assistant for home or portable use. TLEs and the transponder database are sourced from tle.oscarwatch.org.

Getting Started

Pre-built binaries for Windows, macOS, and Linux are available on the GitHub Releases page. After installation:

  1. Configure your station location (lat/long/grid) in Settings.
  2. Select desired satellites and refresh TLEs.
  3. Set up radio and rotator COM ports if using automation.
  4. Focus a satellite via the map or pass list to view live data and frequencies.

Detailed operator guides, keyboard shortcuts, and troubleshooting are included in the app’s Help menu and the repository’s help/ folder. Note that macOS users may need to approve the unsigned app and bundled libraries on first launch.

Supported Hardware Highlights

Radios (serial CAT, native drivers): Icom IC-910/9100/9700/705, Yaesu FT-847/817/818/991 series, Kenwood TS-2000 (beta), with dual-radio options. Rotators: Yaesu GS-232, EasyComm II (SPID/M2/etc.).

The project emphasizes custom native drivers for reliable satellite-specific behavior over general libraries like HamLib.

OscarWatch is still evolving rapidly (recent versions added in-app updates, multi-language support including Japanese, Simplified Chinese, and Brazilian Portuguese, greyline overlays, mutual pass visualizer, and expanded rig/rotator support). Check the GitHub repository for the latest releases, source code, TODO list, and contribution opportunities.

SDR Gen 2 Ad - 2026


Changes to AMSAT TLE Distribution for June 5, 2026

Two Line Elements or TLEs, often referred to as Keplerian elements or keps in the amateur community, are the inputs to the SGP4 standard mathematical model of spacecraft orbits used by most amateur tracking programs. Weekly updates are completely adequate for most amateur satellites. TLE bulletin files are updated daily in the first hour of the UTC day. New bulletin files will be posted immediately after reliable elements become available for new amateur satellites. More information may be found at https://www.amsat.org/keplerian-elements-resources/.

There are no changes to this week’s TLE distribution.

General Perturbations Data Support

AMSAT is pleased to announce that modern forms of what are called General Perturbations data are being disseminated via modern formats including JSON, XML and KVN at https://newark192.amsat.org/gpdata/current/. The reason this change is being made is that we are running out of 5-digit catalog numbers and the TLE format is not viable for satellites launched after July of this year. See https://celestrak.org/NORAD/documentation/gp-data-formats.php for details.

These data are presently considered in beta test for the next two months while hosted on the test server newark192.amsat.org, and we are very open to community feedback at webmaster at amsat.org. Testers may experience outages and errors while we make improvements. We intend to put this into production on our main web server in July as we expect that satellites launched after this summer will require one of the new formats to accommodate longer object numbers. AMSAT will continue to publish TLE bulletins for satellites launched before July 2026 indefinitely.

Satellite Shorts from All Over

+ The U.S. Space Force this week awarded SpaceX a $4.16 billion contract to build a constellation of satellites designed to track airborne targets from orbit. The program is intended to detect and track airborne targets including aircraft, cruise missiles and potentially hypersonic weapons. In the same week, the U.S. Space Force awarded SpaceX a $2.29 billion contract to build a network of low Earth orbit satellites intended to function as a military internet in space. Both deals were among the largest contracts issued this year by Space Systems Command, the Space Force’s acquisition arm. (ANS thanks SpaceNews for the above information.

+ NASA has officially ended the Mars Atmosphere and Volatile Evolution (MAVEN) mission, six months after it lost contact with the probe. MAVEN was the agency’s first program dedicated to studying the Martian atmosphere and its evolution. It launched in 2013 from Cape Canaveral and entered the Martian orbit nearly a year later in 2014. The probe’s primary science mission was scheduled to last one year, but it ended up spending more than 11 years in orbit, sending back data from Mars. NASA even used it as an antenna for the Mars 2020 mission, which brought the Perserance rover to the planet. (ANS thanks Engadget for the above information. Read More: https://www.engadget.com/2187315/nasa-ends-maven-mars-mission/.)

+ PaperSat, an satellite tracking program for the M5Stack Paper S3, an ESP32 based eink device, has been ported to the new M5Stack M5Paper Color. Due to the refresh rate limitations of the color e-ink display, the program has been reconceptualized as a eight satellite next-pass dashboard (in two pages) with alerts to pass events using the on-board RGB LEDs and speaker. PaperSatColor can be found at https://github.com/prstoetzer/PaperSatColor. (ANS thanks Paul Stoetzer, N8HM for the information)

AMSAT to Attend CubeSat Developers Workshop 2026

AMSAT will participate in the CubeSat Developers Workshop 2026 (CDW26), scheduled for April 14–16, 2026, at the Performing Arts Center on the campus of California Polytechnic State University (Cal Poly) in San Luis Obispo, California.

The CubeSat Developers Workshop is the premier annual gathering for the small satellite community. Hosted by the Cal Poly CubeSat Laboratory, the event typically draws more than 500 industry professionals, researchers, educators, and students. Attendees engage in three days of technical presentations, Q&A panels, exhibit booths, and extensive networking opportunities focused on CubeSat and small satellite design, development, testing, launch, and operations. The workshop is especially valuable for newcomers, offering direct access to experienced developers and lessons learned from real missions.

AMSAT’s presence at CDW26 underscores its long-standing commitment to advancing amateur radio in space through CubeSat platforms. AMSAT members and representatives plan to engage with the broader CubeSat community, share expertise on amateur satellite communications (including transponders, telemetry, and ground station operations), and explore collaboration opportunities with universities, educational groups, and commercial developers. This participation helps strengthen ties between the amateur radio satellite service and the wider smallsat ecosystem, where many university and student projects seek reliable, low-cost communication solutions that align with IARU-coordinated amateur frequencies.

AMSAT Satellite Status Page: The Story Behind the New Colors and Satellite Naming Convention

If you’ve visited the AMSAT Satellite Status page recently, you may have noticed the color scheme and satellite naming convention look a bit different. These changes have prompted some questions from the community, and we wanted to take a moment to explain the reasoning behind the updates.

Accessibility First

We received a request to change “Transponder/Repeater Operational” from blue to green, since green often means “good.” That made sense, so we made the change along with a few other minor color adjustments. When we rolled it out, however, we quickly heard from users who couldn’t distinguish “Transponder/Repeater Operational” from “No Signal Heard.” After some research, we learned that red-green color blindness affects roughly 10% of the population, and that’s just one of three prominent types of color vision deficiency, each affecting a different part of the spectrum.

After further research, we adopted the IBM Colorblind Palette, which allows 99.998% of people to reliably distinguish between five colors. While some users have suggested alternative color schemes, many of those proposals would reintroduce the same accessibility conflicts we set out to solve.

Handling Multiple Modes

As satellites grow more capable, many now carry multiple operating modes. Rather than assigning a separate color to each mode, which quickly becomes impractical when a single satellite may support five or six, we’ve given each mode its own line on the Status page. To accommodate this, we updated the naming convention from just the satellite name to the satellite name plus mode. For example, SSTV operations on the International Space Station now appear as ISS_[SSTV]. This approach scales cleanly as new multi-mode satellites come online.

We also renamed “Transponder/Repeater Operational” to “Satellite Active,” which simply means the mode you selected to report on is active. We made this change because “Transponder” and “Repeater” are two-way modes, and an increasing number of satellites are now being launched with interesting one-way modes other than just telemetry and beacons.

We’re always open to suggestions, but please remember, we are all volunteers at AMSAT!

IARU Coordination Requested for VemanaReddySat

A new 1U CubeSat project from Vemana Institute of Technology in Bengaluru, India, has submitted a frequency coordination request to the IARU.

VemanaReddySat  represents a student-led effort focused on educational and technology demonstration objectives. The project involves collaboration with the institute’s engineering departments, building on Vemana Institute of Technology’s growing interest in satellite image processing, CubeSat development, and space-data analytics.

According to the coordination application dated April 9, 2026, the satellite is planned as a 1U CubeSat carrying:

  • A UHF downlink for telemetry and occasional Robot 36 SSTV image transmissions.
  • LoRa capability intended for inter-satellite or experimental links.

The primary downlink will use 9k6 GFSK modulation. The mission aims to provide hands-on experience for students in spacecraft systems, communications, and payload operations while demonstrating low-cost amateur radio techniques in space.

Launch and Orbit Plans

The team targets a mid-2026 rideshare launch opportunity aboard an ISRO PSLV or SSLV vehicle. The planned orbit is approximately 450–500 km altitude with an inclination in the range of 35–60 degrees.

FO-29 Update

Fuji-OSCAR 29 (FO-29 / JAS-2), the long-lived Japanese amateur radio satellite launched in 1996, continues to operate its V/U inverting analog linear transponder under the control of the Japan Amateur Radio League (JARL). Because the onboard batteries have failed years ago, the satellite depends entirely on solar power and can only function when its solar panels are illuminated.

Current Status (April 2026)

  • FO-29 entered a full-sunlight orbit around March 9, 2026. During full-sunlight periods, the satellite experiences no or negligible eclipses, allowing the analog transponder to operate continuously on illuminated passes without scheduled command activations.
  • The first full-sunlight window began in early March 2026 and lasted approximately 40 days.
  • According to the JARL schedule, this continuous operation ends around April 21, 2026, after which the satellite will enter an eclipse period for about one month.
  • A second, longer full-sunlight period is expected from approximately May 20 to mid-November 2026, during which continuous operation should resume.

Transponder Details

  • Mode: V/U inverting linear transponder (SSB and CW only)
    • Uplink: 145.900 – 146.000 MHz (LSB)
    • Downlink: 435.800 – 435.900 MHz (USB)
  • CW Beacon: 435.795 MHz (typically 100 mW)
  • Digitalker: 435.910 MHz FM (rarely activated)
  • The digital BBS (1k2/9k6) remains non-operational.
  • Important Restriction: Digital modes are generally not permitted on the linear transponder due to licensing and operational constraints.

Operating Procedure

  • During eclipse periods (or the transition out of full sunlight), the JARL control team sends specific commands to activate the transponder at designated UTC times. If the transponder does not turn on within about 2 minutes of the command start, the team terminates the attempt.
  • During confirmed full-sunlight periods, no regular command schedule is needed — the transponder stays active whenever the satellite is in sunlight.
  • Operators should always check real-time status via AMSAT Live Satellite Status, OSCAR Status pages, or recent community reports, as voltage instability in the aging satellite can occasionally cause unexpected behavior.

April 2026 Specifics

In early-to-mid April 2026 (while still in the March full-sunlight window), expect the transponder to be available on most or all illuminated passes with no fixed on/off times. After approximately April 21, operation will shift back to scheduled command activations until the next full-sunlight season begins in late May.

The scheduled activations for the eclipse period are:

April
24th 22:22~
25th 21:27~
28th 22:11~

May 
1st 22:56~
2nd 22:00~
3rd 22:51~
4th 21:55~
5th 22:45~
6th 21:50~
7th 22:40~
8th 21:44~
9th 22:35~
15th 22:19~
16th 23:10~

Amateurs are reminded to:

  • Use proper Doppler correction.
  • Follow linear transponder etiquette (listen before transmitting, keep signals clean).
  • Limit uplink power to avoid overloading the transponder (typically no more than a few watts with a modest antenna).

The JARL page provides the detailed historical and upcoming command schedules for eclipse periods across 2025–2026. For the absolute latest status and any updates from the Japanese control team, monitor the official JARL FO-29 page, AMSAT.org, and AMSAT bulletins.

FO-29’s continued operation nearly 30 years after launch remains a testament to robust engineering and the dedication of the JARL team.

Changes to AMSAT TLE Distribution for April 10, 2026

Two Line Elements or TLEs, often referred to as Keplerian elements or keps in the amateur community, are the inputs to the SGP4 standard mathematical model of spacecraft orbits used by most amateur tracking programs. Weekly updates are completely adequate for most amateur satellites. TLE bulletin files are updated daily in the first hour of the UTC day. New bulletin files will be posted immediately after reliable elements become available for new amateur satellites. More information may be found at https://www.amsat.org/keplerian-elements-resources/.

There are no changes to this week’s TLE distribution.

IARU Coordinates Two New Amateur Satellites

The International Amateur Radio Union (IARU) Satellite Frequency Coordination Committee has recently completed frequency coordination for two CubeSat missions: Taiwan’s Lilium-4 and Montenegro’s Luca-01. These coordinations ensure that the satellites can operate without interfering with other space-based communications, paving the way for their upcoming launches and contributions to scientific research, education, and ham radio communities worldwide.

Lilium-4, a 6U CubeSat developed by National Formosa University is set to enhance amateur radio connectivity and optical experimentation in space. The satellite, with callsign BN0YCA, will feature a 1200 bps AX.25 APRS digipeater on 145.825 MHz for global intercommunication among radio enthusiasts. It also includes UHF telemetry downlink at 437.850 MHz and a high-bandwidth S-band downlink at 2405.0 MHz for monitoring an onboard optical payload. Additional capabilities involve a V/U repeater with uplink at 145.980 MHz and downlink at 435.250 MHz, plus GNSS positioning using the L1 signal at 1575.42 MHz. The mission focuses on student-led studies of space-to-ground optical signal acquisition, with unencrypted telemetry encouraging public participation in decoding and link-budget validation. IARU coordination for Lilium-4 was finalized on January 31, 2026, following a submission in late December 2025. The satellite is slated for launch no earlier than mid-March 2026 aboard a SpaceX rocket from Vandenberg Space Force Base, targeting a 510 km polar orbit.

Luca-01 represents Montenegro’s entry into amateur satellite technology, spearheaded by Montenegro Space Research. This 1U CubeSat is designed for educational outreach, equipped with a charged particle sensor and a miniature camera to capture Earth’s surface images. It will transmit special Slow Scan Television (SSTV) images and telemetry data to engage radio amateurs, students, and schoolchildren, using an open protocol for easy reception with affordable equipment. The mission aims to inspire young people in amateur radio and space science, including efforts to image various orbital objects. Downlinks have been coordinated on UHF frequencies: 437.180 MHz primary and 436.150 MHz spare, employing GMSK modulation at rates between 2.4 kbps and 19.2 kbps. Coordination was completed on March 13, 2026, after an application submitted on February 6, 2026. Luca-01 is planned for a Roscosmos launch from the Vostochny Cosmodrome into a 500-600 km Sun-synchronous orbit.

Ten-Koh 2 Satellite With Linear Transponder Deployed

The 6U CubeSat Ten-Koh 2 (also written as Tenkoh-2 or てんこう2) from Japan’s Nihon University was successfully deployed into orbit on March 11, 2026, at approximately 09:34 UTC. The satellite was released from JAXA’s new HTV-X1 cargo spacecraft using the HTV-X Small Satellite Orbital Deployer (H-SSOD) after the vehicle departed the International Space Station (ISS) on March 6 and raised its altitude to around 500 km. This marks the first use of the H-SSOD mechanism for satellite deployment from HTV-X.

Developed by the Okuyama Laboratory in the Department of Aerospace Engineering at Nihon University’s College of Science and Technology, Ten-Koh 2 builds on the legacy of its predecessor, Ten-Koh (launched in 2018). The mission focuses on low-Earth orbit environmental observations to gather data for future space development, alongside in-orbit demonstrations of next-generation communication technologies. Key goals include evaluating high-speed data transmission and enabling global access for amateur radio operators to collect telemetry and experiment with the payloads.

The satellite carries an amateur radio payload coordinated by the International Amateur Radio Union (IARU) and supported by JAMSAT (Japan Amateur Satellite Association):

  • V/U Linear Transponder (inverting, 40 kHz bandwidth):
    • Uplink (LSB): 145.895–145.935 MHz
    • Downlink (USB): 435.875–435.915 MHz
  • Additional Downlinks/Experiments:
    • CW beacon, Digitalker, AFSK 1.2 kbps, GMSK up to 19.2 kbps on 435.860 MHz
    • High-speed experiments (GMSK 4.8–19.2 kbps, 4FSK 38.4 kbps) and photo/picture downlinks on 435.895 MHz
    • 5.839 GHz CW beacon for microwave-band communication demos (SHF experimenters take note—this provides a great target for testing dishes, feeds, and LNAs)

The transponder is expected to operate on a scheduled basis (initially two days per week, with details forthcoming from the team). Operations began shortly after deployment, with the university’s ground station confirming reception of the CW beacon for basic telemetry (voltage, temperature, etc.).

Post-deployment updates from the Okuyama Lab indicate the signal level is currently weaker than anticipated, prompting ongoing monitoring and appeals for reception reports via networks like SatNOGS to aid diagnostics and performance assessment. Early passes over Japan and other regions have yielded mixed results, with some operators reporting no signals yet, while preliminary TLEs (e.g., temporary NORAD 98542) are circulating for tracking.

FO-29 Enters Full Sunlight: Veteran Satellite Sees Renewed Activity in 2026

Fuji-OSCAR 29 (FO-29), also known as JAS-2, the Japanese amateur radio satellite launched in August 1996, has entered a new operational phase as of early March 2026. Now approaching its 30th anniversary in orbit, the satellite—long limited by failed batteries—relies entirely on solar panel illumination for power, meaning it only functions during sunlight periods and shuts down in eclipse.

In February 2026, the FO-29 control team (operated from Japan) continued scheduled activations of the linear transponder, with commands sent on specific dates to turn it on for limited windows. Operators noted the unstable situation due to the satellite’s age, with activations sometimes failing if the onboard voltage didn’t respond quickly enough. The transponder operates in Mode V/u (inverting SSB/CW): uplink LSB 145.900–146.000 MHz, downlink USB 435.800–435.900 MHz, with a CW beacon on 435.795 MHz.

Around March 9, 2026, when FO-29 transitioned into a full-sunlight orbit season. This eliminates periodic eclipses, allowing continuous operation as long as solar panels receive light. AMSAT highlighted this in early February bulletins, noting that shadow duration had decreased dramatically (from ~20 minutes to ~1 minute per orbit by mid-February), leading to the full-sun entry on March 9.

SatNOGS observers reported recent CW beacon and telemetry receptions as of March 12–13, 2026, with stations like EA5WA and DL7NDR logging data. On March 13, 2026, amateur operators reported successful SSB and CW QSOs during passes, including busy activity with calls from Japan (e.g., JO1XOK, JE6TSP), China (e.g., BA4QNR, BD5EUA, BG5FWV), and others (e.g., E27DPX). One operator described a “very busy pass” with multiple contacts, and another logged several SSB and CW exchanges despite windy conditions affecting reception.

AMSAT’s live linear satellite summaries and status pages list FO-29 as active under full sunlight conditions, with the transponder remaining on until voltage drops below safe thresholds—no longer an issue in continuous sun. The digital modes (1k2/9k6 BBS) remain inactive, and the Digitalker on 435.910 MHz is rarely used.

This full-sunlight period offers a welcome revival for one of the oldest active analog linear transponders in the amateur fleet. Enthusiasts are encouraged to monitor, log contacts via the AMSAT OSCAR Status Page, and share reports to help track performance.

Changes to AMSAT TLE Distribution for March 13, 2026

Two Line Elements or TLEs, often referred to as Keplerian elements or keps in the amateur community, are the inputs to the SGP4 standard mathematical model of spacecraft orbits used by most amateur tracking programs. Weekly updates are completely adequate for most amateur satellites. TLE bulletin files are updated daily in the first hour of the UTC day. New bulletin files will be posted immediately after reliable elements become available for new amateur satellites. More information may be found at https://www.amsat.org/keplerian-elements-resources/.

Ten-Koh2 has been added to this week’s distribution.

Many times a school may make a last minute decision to do a Livestream or run into a last minute glitch requiring a change of the URL but we at ARISS may not get the URL in time for publication.  You can always check https://live.ariss.org/ to see if a school is Livestreaming.

As always, if there is an EVA, a docking, or an undocking; the ARISS radios are turned off as part of the safety protocol.

The crossband repeater continues to be active (145.990 MHz up {PL 67} & 437.800 MHz down),  If any crew member is so inclined, all they have to do is pick up the microphone, raise the volume up, and talk on the crossband repeater. So give a listen, you just never know.

​​Service Module radio: Not in APRS configuration; only being used for voice contacts at this time. Default mode is for​​​ packet operations (145.825 MHz up & down) but occasionally used for SSTV (145.800 MHz down)​​.​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​

Ham TV – Configured. ​​ Default mode is for​​​ scheduled digital amateur television operations (2395.00 MHz).

Note, all times are approximate. It is recommended that you do your own orbital prediction or start listening about 10 minutes before the listed time.

The latest information on the operation mode can be found at https://www.ariss.org/current-status-of-iss-stations.html

Satellite Shorts from All Over

+ NASA held a live news conference on March 12 following the Artemis II Flight Readiness Review, confirming the SLS rocket and Orion spacecraft remain in the Vehicle Assembly Building at Kennedy Space Center for final prep work. Repairs to the upper stage helium system (from a quick-disconnect seal issue) are complete, with rollout to the pad expected later this month. The mission targets the first crewed lunar flyby in over 50 years, now aiming for early April launch opportunities (starting April 1) (ANS thanks NASA for the  information. https://www.nasa.gov/2026-news-releases)

+ NASA’s retired Van Allen Probe A (launched 2012) made an uncontrolled reentry over the Pacific west of the Galapagos on March 11. Most of the spacecraft burned up, with a low risk (1-in-4,200) of debris causing harm; its twin Probe B remains in orbit but non-operational. The probes studied Earth’s radiation belts for years. (ANS thanks AP for the  information. See the full article at https://www.kbtx.com/2026/03/11/old-nasa-science-satellite-plunges-back-earth)

+ Roscosmos completed repairs to the damaged Soyuz pad (Pad 31) at Baikonur Cosmodrome after a November 2025 incident where an unsecured service structure fell during launch. Over 150 personnel restored the site; first relaunch (Progress cargo to ISS) targeted for March 22. (ANS thanks Ars Technica for the information.

+  The European Space Agency has confirmed that its Coronagraph spacecraft, part of the Proba-3 solar observation mission, has gone silent following an onboard anomaly in mid-February 2026. The incident led to the loss of attitude control, preventing the satellite’s solar panels from facing the Sun and draining its battery. The spacecraft has since entered survival mode, cutting off all communication with Earth.(ANS thanks MSN for the information.

+ Texas-based Firefly Aerospace is celebrated on March 11 after successfully launching its Alpha rocket for the first time in nearly a year. The mission, called “Stairway to Seven,” was the seventh flight for Alpha, which suffered two major mishaps during 2025. The first occurred during the “Message in a Booster” mission last April, which carried a technology-demonstrating satellite for Lockheed Martin but failed to deliver it to orbit after an anomaly occurred during stage separation. Then, last September, an Alpha first stage exploded on the stand during prelaunch tests. This mishap added months to the mission development timeline as the company investigated a cause and got another booster ready for flight. Alpha Flight 7 achieved nominal performance and validated key systems ahead of the Block II configuration upgrade. This test flight also delivered a demonstrator payload for Lockheed Martin.

+ The second AMSAT Students on The Air Day is scheduled for Tuesday, March 17th. AMSAT’s new initiative for student satellite activity launched on March 3, with operations encouraged on the first and third Tuesdays of each month. A dedicated AMSAT Discord channel supports coordination, sharing, and youth engagement in making satellite contacts. Early participation has been positive as schools and students get on the birds.
